Web conferencing technologies are not standardized, which has reduced interoperability and transparency and increased platform dependence, security issues, cost and market segmentation. In 2003, the IETF established a working group to establish a standard for web conferencing, called "Centralized Conferencing (xcon)".[6] The planned deliverables of xcon include:

In 1996, PlaceWare was founded as a spinoff from Xerox PARC. In November of that year, PlaceWare Auditorium was described in a public talk at Stanford University as allowing "one or more people to give an interactive, online, multimedia presentation via the Web to hundreds or thousands of simultaneous attendees; the presentation can include slides (made in PowerPoint or any GIF-image editor), live annotation on the slide images, real-time polls of the audience, live audio from the presenter and those asking questions, private text and audio conversations in the auditorium's "rows", and other features."[18] PlaceWare Auditorium was formally announced in March 1997 at a price of $150 per simultaneous user.[19]

Let’s face it. Your audience has been conditioned to think “show me the money” by all the scams, gimmicks and otherwise sketchy products out there (and if not that, through Jerry McGuire movie quips for sure). If attendees still haven’t purchased anything several days after your webinar, they are probably thinking, “Your product sounds great, but show me real results from real people like me.”
In April 1999, Vstream introduced the Netcall product for web conferencing as "a fee-based Internet software utility that lets you send business presentations and other graphic information via e-mail to a Vstream server. Vstream converts the content, again using streaming technology, and makes the presentation available for viewing by up to 1,200 people at a time."[28] Vstream changed the company name to Evoke Communications in 2000, with a further change to Raindance Communications in 2002. In February 2006, Raindance was acquired by the InterCall division of West Corporation.
Then you ask them follow up questions to make sure they understood your presentation, what they do not understand, what objections they may have, etc. etc. You will close more sales if you are able to get feedback from clients, and Webinars allow you to see their face, to hear their voice to know how they are feeling about you, your presentation, your company and your products and services.
So instead of meeting with prospects one-on-one, and making dozens of presentations, a better option is to schedule a Webinar for each Wednesday night for example. Just invite your prospects and tell your team members to invite their prospects to the Webinar too. This way, you, as the best presenter gives the best live presentation, and answers questions. Then each person takes over, and talks to their own prospects and directs them to their web sites to sign them up or make the sale. It’s been done for years, and some of the top recruiters benefit greatly from online Webinars.

For the example above, this might sound like, “If you’re tired of people asking to pass you on the golf course, this product is for you. Imagine how it will feel when you start winning games, and accepting business golf match invitations, because you’re confident in your newfound golf game. This program can help you make steady improvement that you’ll begin seeing within a couple of rounds.”
Using Webinar software participants can share audio, documents and applications with webinar attendees. This is useful when the webinar host is conducting a lecture or information session. While the presenter is speaking they can share desktop applications and documents. Today, many webinar services offer live streaming options or the ability to record your webinar and publish to YouTube and other service later.
